Centralised Calender for all VC Groups / iCals for Meetings
Create a calender showing all the up and coming Virtual Chapters meetings, possible extend to events in your region as well. (I believe there's one for UK SQL User groups and Ive seen one for the Powershell Groups, just using Google Calenders)
Being able to get a iCal for meetings. So people don't have to work out the time zone differences.

The Virtual Chapters usually list their meetings on the "Events" page on the PASS site: http://www.sqlpass.org/Events.aspx This page also includes SQL Saturdays and other events. There are improvements in the works that include making it easy to know the event time for your time zone.
